1.0 Introduction
1.1 Background of Study
Tuberculosis (TB) remains a significant public health challenge worldwide, especially in low- and middle-income countries where it causes substantial morbidity and mortality. Despite considerable advances in TB diagnosis, treatment, and prevention, the disease continues to have a widespread impact, primarily due to delayed diagnosis, poor treatment adherence, and co-infection with other diseases such as HIV (WHO, 2020). The global burden of TB is a major public health issue, with the World Health Organization (WHO) estimating that in 2019, 10 million people were diagnosed with TB, and approximately 1.4 million lost their lives to the disease (WHO, 2020). These figures highlight the urgency of strengthening the role of public health workers in the management and prevention of TB.
According to Mills et al. (2019), the role of public health workers in TB control is multi-faceted, involving activities that range from early diagnosis, treatment, and case management to education, community outreach, and policy advocacy. Public health workers are at the forefront of implementing TB prevention strategies, such as the Directly Observed Treatment Short-course (DOTS) program, which ensures that patients adhere to their prescribed treatment regimens (Mills et al., 2019). They also play a key role in case detection, working to identify TB cases in the community, tracing contacts of infected individuals, and providing support to patients throughout their treatment (Andrews et al., 2021).
Barker et al. (2020) stated that challenges persist in TB management and prevention. Public health workers often face issues such as resource constraints, inadequate healthcare infrastructure, and social factors like stigma, which can hinder effective TB control. In many settings, TB is linked to socio-economic conditions such as overcrowded living spaces, poor nutrition, and lack of access to healthcare services, making it difficult to reduce the incidence of the disease (Barker et al., 2020).
Tuberculosis (TB) is a chronic infectious disease primarily caused by Mycobacterium tuberculosis, which primarily affects the lungs but can spread to other parts of the body. It is one of the leading causes of death globally, particularly in developing countries, despite being a preventable and treatable condition (World Health Organization [WHO], 2020). The disease is transmitted through airborne particles when an infected person coughs, sneezes, or talks, making it highly contagious. According to the World Health Organization, an estimated 10 million people fell ill with tuberculosis in 2019, and about 1.4 million people died from the disease globally (WHO, 2020).
Mills et al. (2019) articulated that public health workers play a crucial role in the management and prevention of tuberculosis. Their responsibilities span across multiple domains, including early detection, treatment, education, and the implementation of preventive measures. Effective TB management and prevention depend largely on the efforts of public health professionals such as nurses, doctors, community health workers, and laboratory technicians, who work collaboratively to reduce the burden of the disease (Mills et al., 2019). Therefore, this study seeks to examine the crucial role of public health workers in the management and prevention of tuberculosis.
1.2 Statement of Problems
Investigation revealed that tuberculosis continues to be a major public health issue, particularly in developing countries, where its incidence remains high despite advancements in medical science. In many settings, public health workers are overburdened, leading to gaps in monitoring and supporting patients throughout their treatment process (Mills et al., 2019).
Additionally, stigma surrounding TB and its association with poverty and poor hygiene often leads to a lack of willingness among individuals to seek diagnosis and treatment, further hindering TB control efforts (Dye et al., 2013).
Furthermore, despite the introduction of the Directly Observed Treatment Short-course (DOTS) strategy, many public health workers continue to face challenges in ensuring patient adherence to TB treatment regimens. The lengthy treatment process and side effects associated with anti-TB medications lead some patients to abandon their treatment, which increases the risk of relapse and the development of drug-resistant tuberculosis (Andrews et al., 2021).
1.3 Aim and Objectives of Study
The aim of this study is to examine the role of public health workers in the management and prevention of tuberculosis (TB).
The specific objectives of this study are:
- To assess the specific roles and responsibilities of public health workers in TB management and prevention.
- To identify the challenges faced by public health workers in implementing TB control programs, including resource limitations, training deficits, and social factors.
- To evaluate the effectiveness of current TB management strategies, such as Directly Observed Treatment Short-course (DOTS), in which public health workers play a key role.
- To explore the social determinants of health that impact the spread of TB and how public health workers address these factors in their daily work.
- To assess the impact of public health workers' efforts on the reduction of TB incidence and the prevention of drug-resistant TB.
- To recommend strategies for improving the role of public health workers in TB management and prevention, based on the study's findings.
1.4 Research Questions
Based on the stated objectives, the following research questions guide this study on the effects of poor sanitation on public health and the environment:
- What specific roles and responsibilities do public health workers assume in the management and prevention of tuberculosis (TB)?
- What are the key challenges faced by public health workers in implementing TB control programs, particularly in relation to resource limitations, inadequate training, and socio-economic barriers?
- How effective are current TB management strategies, such as the Directly Observed Treatment Short-course (DOTS), in improving treatment adherence and reducing TB transmission, and what role do public health workers play in this strategy?
- How do social determinants of health, such as poverty, overcrowded living conditions, and poor access to healthcare, affect the spread of TB, and how do public health workers address these factors in their efforts?
- What impact do public health workers have on the reduction of TB incidence and the prevention of multidrug-resistant TB (MDR-TB)?
- What strategies can be implemented to improve the effectiveness of public health workers in TB management and prevention, based on current challenges and gaps in the system?
1.5 Significance of Study
The outcome of this research study will provide an evidence-based understanding of how public health workers contribute to reducing TB incidence and preventing the spread of multidrug-resistant TB (MDR-TB). For healthcare organizations and institutions, the study will provide evidence that will help shape the training and professional development of public health workers.
Furthermore, the findings will open avenues for further research into the socio-economic and cultural barriers to tuberculosis (TB) treatment and provide a foundation for future studies on innovative approaches to improving tuberculosis control, particularly in low-resource settings.
Lastly, this study will serve as a foundation for future research and public health initiatives, ensuring that public health workers are better equipped to combat tuberculosis and improve health outcomes in affected communities.

1.8 Definition of Terms
Public Health Workers:
Public health workers are professionals engaged in the promotion and protection of community health. Their responsibilities include preventing diseases, promoting health education, and managing public health emergencies. In the context of tuberculosis (TB), public health workers are involved in diagnosing, treating, and preventing TB within communities, as well as ensuring that individuals receive the appropriate care and follow-up treatment (Mills et al., 2019).
Tuberculosis (TB):
Tuberculosis is a contagious bacterial infection caused by Mycobacterium tuberculosis, primarily affecting the lungs but capable of attacking other parts of the body. It spreads through the air when an infected person coughs, sneezes, or speaks. TB is a major global health issue, especially in low- and middle-income countries, and can be either latent (inactive) or active (causing symptoms) (Barker et al., 2020).
Tuberculosis Management:
Tuberculosis management refers to the strategies and methods employed to control and treat TB. This includes diagnosing the disease through tests such as sputum smear microscopy and chest X-rays, providing appropriate drug treatment (typically through a regimen of antibiotics), and monitoring patients for drug resistance. Public health workers play a critical role in administering treatment, ensuring patient adherence to therapy, and reducing the risk of transmission (Andrews et al., 2021).
